concrete bodies, and it pertains more especially, among other things, tothe construction of th'e'concrete body andthe metallic anchor" bracketby which such stanchion or other devices may be rrgrdlyfsecured toconcrete bodies; Y My invent-ion 1s further explained by reteren'cc tothe. accompanying drawings, "in

Fig. 3 represents one of the bolts reinoyedfro nthe bracket, and Fig. t represents a vertical section ot a concretebody and the metallic bracket anchoredv therein, showing one of thefastening bolts secured in place. 7

Like parts are identified by the same reference numerals throughout theseveral views. e

1 represents the concrete body. 9 is the'metallic anchor bracket. 4 3, 3are bolts by which stanchions, Ina-ngers and the like are adapted to berigidly secured to the metallic bracket and the cora crcte'body.

The concrete body 1 is provided with a plurality of recesses' l for. thereception ol the heads 5 of the bolts, and the metallica-nchor bracket lis provided with apertures (3 for the reception of the headed ends ofthe bolts. The apertures 6 each comprise a rec- .tangular recess 7'formed for the reception of the body of the bolts, and "thetransverselyarranged portion 8 forthe reception of the.

head ofthe bolt as it is passed through said apertures preparatory touse. The'metaliic anchorbracket comprises a flat central portion, theupper surface of which is flush with the surface of the floor. Thiscentral porembedded in Y the concrete;

tion is elbowed at it s respective'ends'to forni legs extendin suh'stantiallyat right angle;- to theicentral portion and adapted to be Thelower ex tremities of the legs are provided with angular bends forminganchor feet 9, whereby when the legs and feet are embedded in a body .ofconcrete, the bracket will be securely anchored thereto and cannot bewitlidrawn without breaking away the concrete.

The bolt receiving apertures, which are substantially in the form of keyhole slots, are located in, close proximity to the. elbows formed at thejunctions of the central portion andthe downwardly extending legs,-sothat pulling or weaving strains exerted upon the bolts will betransmitted almost directly to the anchor legs without lifting,twisting, or warping the central portion of the I bracket. The'uppersurface of the metallic Figure 1 represents a perspective view of: aconcrete body provided with a metallic bracket, showing bolts forsecuring stan-' bracket 2 is preferably formed flush with the uppersurface of the concrete body, as shown in Fig. l.

It will be understood that the bolts 3' are adapted to be temporarilyinserted in or withdrawn from the metallic bracket without removing suchbracket or changing the construction of the concrete body, whereby whenthe concrete body is provided with the required number of brackets ofpredetermined construction, stanchions, mangers and a grcatwariety ofother devices may, by the use of said bolts, be readily and quicklysecured to such concrete body. Also that by removing the nuts from thethreaded ends of said'bolts, said stanchions or other derices may be dsengaged from the bolts and thebolts in turn disengaged from saidmetallic bracket.

\Vhile I have described the body 1. as being formed of concrete, itwill, of course, he Understood that cement or other equivalent substancemay be substituted therefor.
